Abstract

A method and apparatus for navigating screens in a legacy host system. In a preferred embodiment, requests for specific legacy host screens are received by a server. The server then navigates to the appropriate screen within the legacy host system and retrieves the host screen. Any intermediate screens navigated by the server in reaching the host screen are not displayed to the user. If variable data need be entered to access the host screen, the server sends the user a submitted form on which to enter the appropriate information, which, once entered and sent to the server, is used by the server to retrieve the host screen. Once the host screen has been retrieved, the server formats it into a web page format using a hypertext language and sends the screen to the user. Other screens within the legacy host system are accessed by user selection of selectable links displayed to the user.

Referring now to Fig. 5,, what the figure shows is the block diagram that is used for according to a system of the traditional main system of roaming of the present invention.Navigational system 510 resides in traditional main system 506 to be had on the webserver 508 that is connected.The webserver 508 can realize that traditional main system 506 is positioned on the database 154 with the form of server among Fig. 1 150, and wherein, being connected by IP network 102 between the webserver 508 and the traditional main system 506 provides.The user communicate by letter with navigational system 510 by browser 502, and browser can reside in the form realization such as browser 400 in also can Fig. 4 on the client computer of client computer among Fig. 1 108.

Navigational system 510 is translated into the hot link of a webpage with the main screen face of " system ", and they are sent to browser 502.The user is by being that the URL(uniform resource locator) (URL) of the hot link application address of server 508 is keyed in browser 502 and entered a traditional main screen face with one at the beginning.In this example, the user imports URL and visits server 508, and the latter provides the visit to traditional main system 506.After this initial URL is accessed, open a session, first panel is formatted into the HTML of hot link, and the user profile in cookie or the form data sends back browser with first panel.This head panel is a login panel normally.User profile is sent back and forth with each request, helps request is transformed into the session of opening on the server.All hot links that are sent in user's the webpage refer to get back to http://www.mycompany.com/hostlimker.

Browser 502 shows the tabulation of the hot link 522 of the HREF style of each panel from the representative main system 506 that navigational system 510 is received.An example having represented the navigator window of this web page style among Fig. 6.Each panel in the main system that the user may wish to navigate to is by one selectable " heat " link 602-612 representative, and when hot link was selected by clicking the mouse, navigation system 510 sent one and extracts the suitably request of panel in the main system 506.

Note, if roaming needs variable data between panel, but link will be presented with the form of submission form, and will contain the text field that the user will insert variable data.As shown in Figure 6, with regard to the input data, the user can have two kinds of possible selections.

In a selection, as shown in callup zone 614, but submission form is presented to the user with link, if make that the user wishes to extract this specific panel, but the user just must import data in submission form.In zone another shown in 616 selected, the link that presents to the user, but there is not submission form, to visit these panels and just need the user to import but indicate.If the user selects one in these panels, but navigational system 510 just will generate and send a submission form to the user, be used for the needed variable data of traditional main screen face of input reference user appointment.Behind the user input data, select one to submit to or retrieval options, so that the data of being imported are sent it back navigational system 510, the latter will visit traditional main screen face of being asked with this variable data.

Still referring to Fig. 6, show to the user in the square frame 618 of current panel in this frame window in traditional main system.The content of square frame 618 along with the user in traditional main system roaming and change.In the embodiment of another kind of form, will be presented at from the current panel of traditional main system in the omniselector window 600 independent frame window in addition.

Referring again to Fig. 5,, just a request 520 to new panel is sent to navigational system 510 now by a HTTP(Hypertext Transport Protocol) data stream 516 in case from main screen face link 522, selected a link.When this new panel request was sent out, an implicit expression applet 504 in the browser 502 was also received the notice about this new panel request, was connected (socket connection) so open a road report with server 508 interior data stream objects 512.

After navigational system 510 receives this new panel request, navigate to the main screen face.Directly be connected if having one between current panel and the main screen face, then the interior grand bean of navigational system 510 is with regard to the required proper data of input reference main screen face.If must visit several panels in face of the visit main screen, then carry out suitable input, so that realize visit to the main screen face at each panel.Variable data could be passed through some middle panel or directly be visited the main screen face if desired, just obtain this variable data from the user, as mentioned above, but its method is the submission form that sends a request proper data, but or will be somebody's turn to do submission form as containing a part of pointing to the initial panel of the connection of various panels in traditional main system.

Connection between each panel in grand in the navigational system 510, the connection that is used for verifying next panel that provides of each system just as at present.On the contrary, the grand beans (macro bean) in the navigational system 510 contain record and use the intelligence of link, if there be final the connection, just cross a plurality of panels and arrive the target panel, are parked in the target panel then.In other words, each next panel of regulation in a grand panel piece (macro screen block) all contains from current panel piece and roams into the next default action that will carry out.By the sample of representing among Fig. 7 A-7C in grand＜nextscreen〉label can see its example, hereinafter will go through.

In case obtain visit to the main screen face, the main screen face is just extracted from traditional main system 506, and be reformatted into and comprise a kind of hypertext language that main chain connects, such as extend markup language (XML) or HTML(Hypertext Markup Language), make the form that this panel can webpage show to the user by browser 502.Data stream object 512 notice implicit expression applets 504 panels upgrade, and navigational system 510 is that the main screen face of form sends to browser 502 by http traffic 516 with the SGML with what ask.Browser 502 shows traditional main screen user oriented of being asked then.

Therefore, the invention provides by the Internet application programs, service and/visit of data, and when creating them, do not consider originally by the Internet to the user provide these application programs, service and/data.The present invention roams between panel with " heat " link example of fine understanding, also makes traditional main system visualize/modelling.In addition, the present invention makes the user can browse this panel in grand everywhere, and gets rid of the notion that run macro is finished particular task.In fact, a whole addressable main system of representative is big grand always in operation.Like this, the user to how to issue appropriate command on suitable panel need not to accept training or this knowledge is arranged, and just can use traditional main system.The user needs only browing system everywhere just as browsing the web page that links on the world wide web (www) everywhere, is absorbed in data rather than navigation.

The present invention also allows the user to skip over over several panels, only the user's interest panel is presented to the user thus.This is too important concerning the very valuable hand held equipment of bandwidth and other wireless device.For example, the user can leap to the puborder search from ready prompt, and need not to see five panels therebetween.Other advantage is conspicuous for those skilled in the art.

Referring now to Fig. 7 A-7C,, expression is according to a grand example that is fit to be provided at navigation (navigation) around traditional main system of the present invention among the figure.In this example, grand bean is equivalent to the grand bean of IBM Host On-Demand (HOD).Grand bean is a program design object, when being connected to a master terminal emulator program design object (being the Sessionbean of IBM HOD), according to the subscriber-coded script that offers grand bean (being the XML sign indicating number), automatically roams in the main screen face.Each program block 702-718 contains and is useful on from traditional main system the XML sign indicating number that a specific panel roams into other panel in traditional main system.Each program block 702-718 contain expression panel name, panel whether be transition and panel be inlet or outlet panel one.Each program block 702-718 only just carries out when sending current panel to new panel request corresponding to program block top panel name label from it.The transition label indicates whether this panel is shown to the user.If the transition label is true, then suitable clauses and subclauses is presented to the user, but do not show this panel to the user.Like this, as mentioned above, the user does not have the burden of reading a large amount of panels unnecessaryly, and has saved bandwidth because of not transmitting these panels to client computer.

Each program block 702-712 also contains next panel (nextscreen) label, and it determines which panel the user wishes to see.For example in program block 704, next panel label of correspondence " Puborder.search " and corresponding " ready " is arranged.According to user's selection, input value " [pf9] " or input value " [pf3] " that each corresponding function key is selected will be sent to traditional main system, so that can extract suitable panel.Like this, need not the user and know and just can navigate to suitable panel with which function key or button, just the panel of being asked can be extracted.This information be included in this grand in.

If visit main screen face does not need variable data, perhaps receive variable data from client computer, server is just imported proper data and order, to obtain in case of necessity by the various middle panel visit main screen faces (step 812) of roaming.Then, the main screen face is extracted (step 814), and server will comprise the main screen face that points to the hyperlink of other panel in traditional main system, be formatted into the SGML that browser can be read, such as XML or HTML (step 816).Server sends to the main screen face of formatization client computer then and feeds to the user and show (step 818), and process finishes at this.

Referring now to Fig. 9,, the flowcharting of this figure is according to the method for roaming and reading traditional main screen face from the angle of client computer of the present invention.At the beginning, the user sends the request of a traditional main system of visit to server.Client computer receives the user who has formatd then and wishes the main screen face (step 902) that points to the hyperlink of various panels in traditional main system that contains read.Then, client computer is waited for user's input (step 904).Browser determines whether the user has selected a hyperlink (or " heat " link) (step 906).If no, browser just continues to wait for user's input (step 904).

If the user has selected a hyperlink, browser determine selected be which hyperlink (step 908) and to server send one in traditional main system should the new main screen face of selecting request (step 910).Browser wait for then from server receive user-selected format traditional main screen face (step 912), show this panel (914) to the user then.

This information can show in the Lower Half of the window frame that is positioned at of navigation panel, perhaps shows in an independent window frame.Point to the hyperlink of various panels in traditional main system, can show together with data mixing from traditional main system, or with these two kinds of content regions separately and show separately.Within the scope of the present invention, also may adopt other to present the data of traditional main system and the method for navigational tool to the user.

It should be noted that, although be in the context of global function data handling system, describe of the present invention, the common skilled person of this area understands, method of the present invention can the computer readable instructions medium form and various forms configuration, no matter what particular type the actual signal bearing media that is used for carrying out this configuration is, the present invention is equally suitable.But the example of computer-readable medium comprises the medium (such as floppy disk, hard disk drive, RAM and CD-ROM) of record type and the medium (such as numeral and analog communication links) of transport-type.
